osTicket

osTicket is an open source customer support ticketing system, developed and maintained by Enhancesoft, that organises, manages and archives incoming support requests. It has been widely adopted for many years by organisations looking for a straightforward, cost-effective alternative to commercial help desk platforms. The problem osTicket solves is the disorder that arises when support requests arrive through shared email inboxes, phone calls and web forms without a consistent way to assign, prioritise and track them. By converting every request into a ticket with a unique reference, the system ensures that issues are recorded, routed to the right team and followed through to resolution. Its approach centres on simplicity and flexibility: organisations can self-host the software on standard PHP and MySQL environments at no licence cost, or choose a hosted cloud edition supported by the vendor.

Key features include email piping and web form ticket creation, custom fields and forms, help topics that route tickets to departments, and ticket filters that automate assignment and prioritisation. Agents can use canned responses, internal notes and collision avoidance to prevent duplicated work, and service level agreement plans help track response and resolution times. A customer portal enables users to submit and follow up on tickets, while a knowledge base and frequently asked questions area supports self-service. Role-based permissions, departments and teams give administrators control over access. Reporting provides insight into ticket volumes and agent activity, and an API and plugin system allow integration with other systems, including authentication providers. The open source community contributes extensions and support resources. osTicket is used by small and medium-sized businesses, educational institutions, government bodies, non-profit organisations and internal IT departments that require a reliable ticketing system without complex configuration. Pricing for the hosted service starts from around USD 12 per agent with a free trial; the listing does not include a free version, although the self-hosted open source edition is freely downloadable.
